BREEZE COLLECTOR.

' Application filed March 2,1925. Serial No. 12,621.

This invention in general relates to devices for catching dust and more particularly to that type of devices termed breeze arresters or collectors for the dust, cokebreeze or dbris delivered from and generated by water or carbureted Water gas machines.

The ordinary type of machine for manufacturing water gases or carbureted water gas, is usually charged withmaterial from a door in its upper or top portion. In producing gas withthis type of machine a relatively high draft exists Within the machine. N w, obviously, the moment the charging door is opened to replenish the materials within the gas making machine, a compara-v tively great blast is caused to be blown up wardly through the door in which blast is suspended small particles of carbon and other matter which are usually referred to as coke-breeze. A considerable quantity of gas is also drawn along with 'theblast as it escapes from the machine.

N ow if this coke-breeze expelled from the gas machine is discharged directly into the atmosphere, it not only pollutes the air of he community, but it settlcs'on the, buildings and ground thereabout. Furthermore, by allowing the coke-breeze to be expelled into the atu osphere, it means that the machine is losing raw material or fuel and hence is unable to produce the maximum amount of is for agiven quantity of raw. material. 150, the gas that makes its escape with the blast, and hence it should not be discharged into the room where the gas machine operators are located.

An object of the present invention is to provide an improved breeze collector or arrester of simple compact and inexpensive construction which may be quickly and the blast are permitted to make their escape into the atmosphere.

A further object of the invention is to provide a device of the above character in which the particles of carbon suspended in the blast are deflected completely intoa suit is both poisonous and inflammable,

easily applied to the usual gas manufactur- 'able container for future consumption, thereby resulting in a substantial increase in efficiency of the gas manufacturing equipment.

A still further object of the present invention is to completely eliminate any danger of the gases discharged from gas making machines, making their entrance into the room where the operators are working.

I am aware that it is old to collect the particles of matter discharged with the blast in a gas machine, and to convey the gases into the atmosphere. The devices heretofore designed to accomplish these two features,

to accomplish this purpose, have been able to properly collect particles of matter car- I ried out by the outrushing gases, due to the fact that considerable amounts thereof in being deflected were carrled out by the escaping gases to the atmosphere. Then again. a when the door of thegas machine was closed and the blast again enclosed, deflected particles of matter were freeto fall back down the path over whlch they were forced by the onrushing' blast, due to gravity, and hence were not collected in the container devised therefor. Moreover, the devices have heretofore been objectionable in that the particles ojf matter were deflected too many times before; reaching the ultimate downward path over which they gravitate, and, hence, substantial quantities of this matter were lost ontlie rebound.

I propose in accordance with the features of the present invention to provide a device of simple construction preferably made of sheet metal and, comprising a minimum number of bends or forms. In my device, after the particles of matter in suspension are once deflected, they are free.

on the rebound to gravitate over a suitable path into a container devised therefor. Also, the gases escaping with the blast are not permitted to enter the atmosphere until the particles of matter in suspension have been deflected and are free to grav1tate. In other words, at the time the gases are permitted to escape from the stack the particles are already on their downward path, falling due to gravity, and hence, inasmuch as this path is the one of least 'resistaiice,theparticles will continue over this path into the container and will not be carried out by the outgoing gases.

Other objects and advantages of the present invention will more fully appear from the following detailed descriptiomtaken in connectionwith the accompanying drawings, which lllustrate one embodiment thereof,

and in which;

Figf 1" is aside elevation of a gas machine to whichfis-applied a breeze arrester similar partsthroughout the several views,

10 denotes a gas manufacturing machine which may be offany usual or suitable construction. The machine is positioned in a room, referred to generally hereinafter by reference numeral 11,provided1'with suitable beams 12, and a. roof 13. Located in the room 11 adjacent machine 10, is a receptacle or container 141, into which the coke-breeze is delivered, as will be more fully" described hereinafter. The coke-breeze in the container 14: may be withdrawn whenever desired through a discharge pipe15, passing through the floor lt} into the room below (not shown). l

The top portion 17 of the gas machine proper is provided with a door 18 through which material is admitted into the furnace for charging same. Positioned immediately over the door 18 is a funnel shaped or flared end 19 of a stack 20 passing through, both'thebeam s 12 "andthe roof 13' The end19 of the stack 20 is supportedandspaced from the'top 17 of the gas machine 10 suitable "supporting elements 21 The other endjofthstack20 is provided with an elbmv-hke member or lateralbend 21 provided witha flared end or discharge orifice221 This member 21 may, if desired; be detachably mounted to the stack 20. bend provided for by hi m mb r 2 is sl h je 'a erf ll fi th r' er 1531 shtahsl lb w L c t adjacent the flared end 22 of the member 21 is a tapered member 25 which gradually diminishes in size until its discharge orifice 2stis approximately the same as that of a downcomer pipe 25 to which it is suitably connected. The large end of the member 25'is"sp aced from but adjacent to the flared end 22 of the member 21 and is adapted to receive particles of matter discharged therefrom, or rather gravitated therefrom, as will be more fully described hereinafter.

' The member 25 is provided and equipped with another outlet 26 which is connected by a smallpipe 27 to the pipe 25 intermediate its ends. The pipe 25 is in communication with a vent pipe 29 through the means of a small section of piping 30 connected to the pipe 25 near its upper end and to the pipe 29 intermediate'its ends. The vent pipe 29 is of usual construction and providesan escape outlet for the gases which might get into the member 25. The greater part of the gases will be permitted to 'es'cape through the/means of the space separating the flared end 22 from the member 25. Both the pipes 29 and 25 terminate at their lower ends in the dust collector 14.

Aspreviously mentioned, the parts constituting the breeze arrester may be made ofsheet metal and suitable metal shapes. Due to the simplicity of design of my structure, it. may be produced'at a relatively small cost and may be applied very readily to the ordinary gas manufacturing machine. The onlyineinbers in my construction of unusual'or new design, are the members 21 and 25 which, although new, are of a simple construction. Suitably supported over the members 21 and 25 is a cover 35 for preventing rain from entering these members' r The operation of this mechanism is as follows l I Upon the door 18 being opened, the blast arising from the furnace is of suflicient velocity to carry the coke-breeze particles along with it, as well as certain quantities of gas, as previously explained. These breeze particles are carried in a state of suspension in the blast, up through the stack 20, which is positioned to receive the entire effect of the blast. The blast upon reaching the upper part of the stack 20, strikes the upper portion 40 of the lateral bend or memberj2l, and rebounds, or rather is'deflected'out"through the orifice provided for by theflared end 22 of the member 21, Qbviously, upon the particles of'colre or. namely, the breeze coke, coming in contact witlrthe portion 10 of the member 21, they are deflected from their true course and lose practically all their initial velocity; After hay ingrebounded fromthe portion 10, they gravitatedown the member21 and fall into All the member 25 by their own weight. The majority of the air and gas which accompanies the colre-breeze particles are free to escape'trom the member 21 into the surrounding atmosphere. 7 matter in the member 25 gravitate-along the incline thereof and are discharged through the opening 26 and the orifice 2d into the downgoing pipe 25. The member has just a sui-"licient amount of incline to permit the particles of matter discharged therein to gravitate along its inner surtac to the two openings thereof.

Practically theentire amount of gases arising in the stack 20, as previously mentioned, are discharged between the space separating the inei'nbers 2i and 25, but in order to provide an escape for any gases which might get into the pipe 25 and the receptacle I l, I provide a vent 29 which permits any such gases to escape into the atmosphere externally of the room 11.

It is evident that the construction of the member 21 is such that the particles of matter deflected thereby are tree to rebound rom in a direction such that the angle therei o1 incidence is substantially equal to the angle of deflection. particles of matter rebound from the portion l0 ot' the member 21, they will be de livered into the member 25 practically without the need of any assistance of the accompanying gases, due to the fact that the end 22 of the member 21 is turned downwardly and. hence the deflected particles of matter are free to gravitate in the member rather than be forced there by the initial velocity of the accompanying gases Then, too, the blast upon reaching the lateral bend 21 tends to follow the upper part oi the bend, whereas, the particles 01 matter tend to drop to the bottom of the bend and are free to thereafter gravi ate into the receptacle The cover supported over the members 21 and 25 in such a manner as to completely cover the space separating the ends of the two members from the clownponr ot rain, snow and sleet. Olwiously, he ot the two members may be comletcly enclos d by a cover provided with suitable openings for the escape of gas without departing from the present invention. in tact, this maybe desirable where the natural elements such as wind are unusually turbulent and powerful, so as to prevent any of the particles of matter discharged in the member 25 from being blown into the atmosphere. But as a general rule, the ordinary wind will only tend to augment the downward flow of the matter discharged in the m mber 25, bl wing same completely down the pipe 25 into its receptacle I l.
